For Simon Gilroy, sometimes seeing is believing. In this case, it was seeing the wave of calcium sweep root-to-shoot in the plants the University of Wisconsin-Madison professor of botany is studying that made him a believer.

(Phys.org) —Zoologists and bioengineers from Trinity College Dublin have identified over 1,000 genes whose responses change markedly when embryos are not able to move freely in the womb. The discovery will help scientists ...

The Wnt/β-catenin signaling pathway and microRNA 335 are instrumental in helping form differentiated progenitor cells from stem cells. These are organized in germ layers and are thus the origin of different tissue types, ...

In the U.S., someone suffers a heart attack every 34 seconds—their heart is starved of oxygen and suffers irreparable damage. Engineering new heart tissue in the laboratory that could eventually be implanted into patients ...

(Phys.org) —Kumu Networks, co-founded by Stanford professor Sachin Katti, has announced that the company has developed technology that allows for full duplex wireless communications—it lets, the company claims, a radio ...

The beating of flagella is one of the basic principles of movement in the cellular cosmos. However, up to now, scientists were unsure as to how the movements of several of these small cellular appendages are synchronised. ...

Protein synthesis in the extensions of nerve cells, called dendrites, underlies long-term memory formation in the brain, among other functions. "Thousands of messenger RNAs reside in dendrites, yet the dynamics of how multiple ...
